Hi,

you neeed to set DNS resolver on this server:

edit /etc/resolv.conf and put your DNS server, for example

nameserver 10.10.10.10

Vitaly.

Hi,

if you have a DNS daemon on the same machine, it is likely that this named crashes after some time and prevents squid from getting a name resolution.

If you are using a DNS server on a remote machine, possible your (dial in ?) connection is cut off or there is a firewall on your/remote machine which blocks some of the packets.

Another possibility is that you are querying more than 1 nameserver (round-robin) and of the DNS servers is not working properly. To check against this condition, do several nslookups on the name of the nameserver and have (if applicable) a look into your named.conf (section forwarders).

HTH,

Christoph
